    Hence, work done = 287.54 J

    Explanation:

    Given dа ta:

    angle of ramp with the ground θ = 20°

    force applied = 76 N

    work done on the crate to slide down 4 m down the ramp

    W = F*d cosθ (only the cos component of the force will slide the crate down)

    W = 76*4*cos20 = 287.54 J
